Embodiment Construction

[0023] The present invention provides a PLC networking method through device unique code pairing and identification card pairing. In order to make the present invention more obvious and easy to understand, the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0024] like figure 1 As shown, the multi-connected air conditioner PLC (power line carrier communication) communication networking system of the present invention includes: one air conditioner outdoor unit, several air conditioner indoor units and several wire controllers. Any indoor unit of the air conditioner can be matched with a wired controller. When installing multi-connected air conditioners on site, the number of air conditioner indoor units and wired controllers can be determined according to user needs. A PLC communication module is installed on all air conditioner outdoor units, air conditioner indoor units and wired controllers.

Abstract

The invention discloses a PLC networking method for pairing through equipment unique codes and identification cards. The method comprises the steps that S1, a monitor sends network codes generated byoutdoor unit physical address information, the indoor unit equipment unique code and the wire controller equipment unique code to outdoor units CCO; S2, the monitor broadcasts power-on passwords and an indoor unit and outdoor unit pairing table towards all the outdoor units CCO, the outdoor units CCO obtain password information correspondingly, and networking of the outdoor units CCO and an indoorunit is completed; S3, the blank identification cards of a wire controller are inserted into the outdoor units CCO to form the network codes as well as an indoor unit-wire controller pairing table composed of the indoor unit equipment unique code and the wire controller equipment unique code; and S4, the identification cards are inserted back into the wire controller, the wire controller has access to a PLC network, and pairing of the indoor unit and the wire controller is completed at the same time. By means of the PLC networking method, networking of indoor unit and the outdoor units of anair conditioner and pairing of the indoor unit and the wire controller can be completed in a zero-intervention mode, cost is reduced, installation is simple, and maintenance is convenient.

Description

technical field [0001] The invention relates to the technical field of PLC communication, in particular to a PLC networking method through device unique code pairing and identification card pairing. Background technique [0002] Multi-line air conditioner refers to the "one-to-n" air conditioner unit, that is, one air conditioner outdoor unit is connected to control two or more air conditioner indoor units. For example: in an air conditioner unit, the outdoor unit of the air conditioner transmits refrigerant (heating agent) to two or more indoor units of the air conditioner through the pipeline, and the outdoor unit of the air conditioner controls the circulation amount of the refrigerant (heating agent) and enters the room. The flow rate of the refrigerant (heating agent) of the air conditioner can meet the temperature regulation requirements of the indoor unit of the air conditioner. Each air conditioner indoor unit can control the air conditioner outdoor unit through ind...
